Schlage B520-242 – Frequently Asked Questions

1) What is the Schlage B520-242 lazy tailpiece used for?
The B520-242 is the tailpiece that transfers the turn of a Schlage interchangeable core cylinder to the lock mechanism. It is a 2.2 inch single cylinder lazy tailpiece used with B250/460 IC core cylinders, H Series IC core cylinders (except H160), and S200 Series IC core cylinders built before February 26, 2008. If a key turns in the core but the bolt does not move, the tailpiece is usually the part being replaced.
2) What door thickness does the Schlage B520-242 tailpiece cover on a B250 or B460 deadbolt?
With B250/460 IC core cylinders the B520-242 covers doors from 1-5/16 to 2-1/8 inches, and also doors over 2-5/8 up to 3-1/8 inches. Doors falling between 2-1/8 and 2-5/8 inches are outside what this length handles.
3) I have Schlage S200 Series locks in my building. Does this tailpiece fit them?
Only the older ones. The B520-242 applies to S200 Series IC core cylinders manufactured before February 26, 2008, on doors 1-3/8 to 1-5/8 inches thick. S200 cylinders made after that date use a different tailpiece, so check the manufacture date before ordering for a legacy retrofit.
4) Is the B520-242 for a single cylinder or double cylinder lock?
Single cylinder. The 2.2 inch length is sized for single cylinder IC core applications, so a double cylinder deadbolt with a keyed core on both faces needs a different tailpiece.
5) Can one tailpiece part number cover a mixed building of Schlage IC core locks?
Across a lot of it, yes. The B520-242 spans three Schlage IC core families, B250/460, H Series other than H160, and pre-2008 S200, which is why facility and MRO buyers keep it on the shelf. What decides it on each opening is door thickness, since each family has its own stated range for this length.
6) Is the Schlage B520-242 an OEM part or an aftermarket copy?
It is a Schlage part built to OEM specification, model B520-242, intended for commercial mechanical lock systems rather than residential grade hardware. For a facility standardized on Schlage IC cores, it keeps the original fit and engagement in the cylinder.
